BOOTLOOP "UMIDIGI" how to fix ?

umizprohowtofix

This night my Umi Z Pro was hanging in bootloop. I was wondering that the alarm clock was not ringing this morning. So I saw UMIDIGI - Black Screen - UMIDIGI - Black Screen ... and so on.
Now I was trying to repair with flash method. But it seems to stuck ... no boot.
Tried ROM from 20170408, 20170321. Even a full download with SP tool did not help. So flash process always ok.
I'm now testing with DRAM flip test.
It seems that not the flash is the problem.

If somebody has an solution, please HELP!!

Did you check all partitions?
Also you can try recovery or factory mode and clear/wipe of cache, eMMC or factory reset.
Then try restart phone again.
If still is not fixed you can try format + download on SPFT. But then you need use SN writer to restore your IMEI numbers.

Also you can disconnect battery for few minutes but this will void warranty.
